Description

Technical Field

[0001] The invention relates to the technical field of preparing multi-layered microfiber leather, and in particular to a preparation process and production equipment for a waterborne polyurethane sports shoe leather base. Background Art

[0002] Compared with solvent-based microfiber cloth, the preparation method of water-based microfiber cloth is more environmentally friendly. Water-based polyurethane uses water as a dispersion medium. There is no solvent volatilization during the production process, and there is no health hazard to operators in the production workshop. Therefore, water-based polyurethane is increasingly used in the field of synthetic leather. Existing water-based polyurethane synthetic leather preparation processes and preparation equipment, such as the water-based bio-based synthetic leather preparation device and process disclosed in Patent Document 1 (CN117681537A), include a main composite layer body and a secondary composite layer body pressed together, and the glue is injected between the main composite layer body and the secondary composite layer body by a main glue injection roller and a secondary glue injection roller. It is operated by a synchronous glue injection mechanism, and a plurality of telescopic glue injection bodies are rotated by a coaxial synchronous drive to achieve an interval telescopic action, which realizes the convenience of glue injection. However, it does not take into account the possibility of misalignment between the main composite layer body and the secondary composite layer body pressed together, and the folds may be skewed during transportation, thereby affecting the quality and processing of the subsequently formed synthetic leather; for example Patent document 2 (CN118876566A) discloses a laminating rolling machine that can perform laminating and rolling of multi-layer films or layered materials. It has several conveyor belts and two pressure rollers arranged between the hot pressing roller and the cooling roller. By driving the pressure rollers to rotate, the composite materials are compacted. In addition, several needle-punched parts are arranged on the pressure rollers. The needle-punched parts penetrate into the material through the gaps formed between adjacent conveyor belts, thereby improving the bonding effect. However, the laminating rolling machine also has the problem that if the mutually pressed material layers are skewed, misaligned or wrinkled, they cannot be corrected or straightened, which also affects the quality and processing of the subsequently formed synthetic leather.

[0003] In summary, although the prior art already has preparation processes and equipment for the preparation of multi-layer microfiber leather and water-based polyurethane synthetic leather, the focus is mostly on how to better perform adhesive treatment on the composite layer between two or more layers. The problems of wrinkles and deflections that occur between the composite layers between two or more layers during transportation or transfer are not considered. In addition, during the needling operation, affected by the size of the conveyor belt, the needle-punched parts can only be inserted through the gaps between the conveyor belts, which makes the needling density insufficient and the needling density cannot be flexibly adjusted. For this reason, the present application provides a preparation process and production equipment for water-based polyurethane sports shoe leather base that can be pressed together with two or more composite layers, avoid wrinkles in the outer layer when the multi-layer composite is laminated, avoid tilting of the multi-layer composite during transportation or winding, and can flexibly control the needling density.

[0018] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art:

[0019] 1. In the preparation process of the water-based polyurethane sports shoe leather base of the present invention, a plurality of belt pressure roller groups that can be overlapped are used to press the multi-layer base fabric. The multi-layer base fabric is arranged in an S shape and wound in the plurality of overlapping belt pressure roller groups. Each belt pressure roller group includes a swinging base fabric stretching component that can stretch the surface of the multi-layer base fabric from the inside to the outside, and also includes a dynamic needling component that can adjust the spacing between the circular belts according to actual needs to adjust the needling spacing. It also includes a component that can adjust the left and right deflection when the multi-layer base fabric is transmitted, thereby ensuring the accurate transportation of the multi-layer base fabric and the fitting quality of the multi-layer base fabric. In addition, the base fabric correction component can also adjust different transmission speeds when the transmission speeds of different cross sections of the multi-layer base fabric are different, further ensuring the smooth transmission of the multi-layer base fabric. The belt pressure roller group can be selected in different quantities according to actual needs, and the multi-layer base fabric is arranged and wound in an S shape, so that the multi-layer base fabric can be stretched and needled on both sides, which can better improve the pressing effect of the multi-layer base fabric.

[0020] 2. The first heat-insulating pressing roller group and the second heat-insulating pressing roller group of the present invention both include a roller inner core and several belt clutch outer guide sleeves movably arranged on the outside of the roller inner core, and several belt clutch outer guide sleeves each include several one-way locking assemblies. The one-way locking assemblies can be used in conjunction with the base cloth correction assembly. When it is necessary to speed up the area where the transmission speed of the multi-layer base cloth is slow, the base cloth correction assembly can engage the annular belt in the corresponding area, accelerate the rotation speed of the base cloth correction assembly, and make the annular belt generate a transmission speed faster than the rotation speed of the roller inner core, and finally unlock the one-way locking assembly. The annular belt here generates a faster rotation speed, thereby speeding up the area with slow transmission speed, so that the entire multi-layer base cloth can be transmitted as a whole during transmission, better ensuring the pressing and forming of the multi-layer base cloth.

[0021] 3. The dynamic needling assembly, swinging base fabric stretching assembly and base fabric deviation correction assembly of the present invention all include a base fabric processing roller group, and a plurality of telescopic rods are arranged outside the base fabric processing roller group. The plurality of telescopic rods are arranged outside the inner telescopic driving rod group. The base fabric processing roller group also includes an outer roller cover provided with a plurality of protruding holes and slots. The telescopic rods extend from the protruding holes and slots, and an intermediate slot is provided on the inner side of the circular belt. The telescopic rods can be inserted into the intermediate slot by extending the telescopic rods. The action of the inner telescopic driving rod group drives the telescopic rods to slide along the axial direction of the base fabric processing roller group, thereby adjusting the spacing between adjacent circular belts, realizing the adjustment of the needling distance, or realizing the stretching of the outer surface of the multi-layer base fabric, and also realizing the correction of the left and right deviation of the multi-layer base fabric.

[0022] 4. The inner telescopic drive rod group includes an inner telescopic fork rod group and several synchronous telescopic drive components. The inner telescopic fork rod group consists of several scissor rods, transverse connecting rods and sliding sleeves. The synchronous telescopic drive component includes an input power shaft, an intermediate synchronous transmission mechanism and several output rotating shafts. The input power shaft can be connected to the several output rotating shafts through the intermediate synchronous transmission mechanism. The input power shaft can be driven to rotate by the action of the transverse connecting rod, and the transverse connecting rod, the scissor rod and the sliding sleeve form a scissor mechanism. By controlling the rotation of the scissors, the vertical sliding of the transverse connecting rod is realized. The vertical sliding of the transverse connecting rod is converted into the rotation of the input power shaft. The rotation of the input power shaft realizes the rotation of the output rotating shaft through the rotation of the intermediate synchronous transmission mechanism. The rotation of the output rotating shaft is finally converted into the telescopic action of the telescopic sleeve, thereby realizing the synchronous telescopic movement of the telescopic needles on the output rotating shaft and the input power shaft, and also realizing the synchronous telescopic movement between the telescopic needles on different synchronous telescopic drive assemblies. In addition, the above arrangement of the inner telescopic drive rod group realizes a compact structure while also being able to achieve a good synchronization effect.

DETAILED DESCRIPTION

[0053] The embodiments of the present invention are described in detail below with reference to the accompanying drawings. Example 1

[0054] A preparation process of waterborne polyurethane sports shoe leather base comprises the following steps:

[0055] a. Preparation of multi-layer base fabric:

[0056] A waterborne polyurethane mesh is used as the middle layer, and a microfiber non-woven fabric is used as the upper and lower surface layers. Glue is applied between the middle layer and the upper surface layer, and between the middle layer and the lower surface layer. The layers are initially pressed together by a pressing roller to form a multi-layer base fabric 1. The layers are then pressed together and needle-punched by a base fabric pressing device 2 to form a processed multi-layer base fabric 1.

[0057] b. Impregnation of water-based polyurethane slurry:

[0058] The treated multi-layer base fabric 1 is immersed in an aqueous polyurethane slurry, wherein the components of the aqueous polyurethane slurry include aqueous polyurethane, a wetting agent, a thickener, a leveling agent, a defoaming agent, and deionized water, and the solid content is 20%-40%, the room temperature viscosity is 2000mPa·s to 2500mPa·s, and the liquid carrying rate is 100%-200%; after curing, a water-based polyurethane sports shoe leather base is obtained;

[0059] The hard segment diisocyanate of the waterborne polyurethane is isophorone diisocyanate (IPDI), the soft segment is polycarbonate diol and a small molecule diol, and the hydrophilic chain extender is dimethylolpropionic acid. The specific synthesis method is to first vacuum dehydrate the polycarbonate diol, then mix and stir it with isophorone diisocyanate (IPDI), and then add a catalyst to react until the polycarbonate diol is completely consumed and there is a surplus of isophorone diisocyanate (IPDI). Next, the temperature is lowered to adjust the viscosity, and a small molecule diol (1,4-butanediol) and dimethylolpropionic acid are added. The reaction is continued until the NCO mass fraction reaches 4.5%. The temperature is then lowered and TEA is added for neutralization reaction. After that, deionized water and EDA are added, emulsified and dispersed, and the organic solvent is removed to obtain the waterborne polyurethane. The above specific preparation method of the waterborne polyurethane is known in the art.

[0064] like Figure 10 、 16 -24, the number of the synchronous telescopic drive components 29 is M+K.

Each output rotating shaft 40 is provided with a telescopic sleeve 1 42 on the outer sleeve. The telescopic sleeve 1 42 cannot rotate along its own axis. The lower end of the transverse link 35 is provided with a telescopic sleeve 2 45. The outer end of each input power shaft 37 is provided with a telescopic sleeve 2 45. When the middle rear scissor rod 1 and / or the middle front scissor rod 1 rotates, the transverse link 35 is driven to slide axially toward or away from the inner rod 30. The axial sliding of the telescopic sleeve 2 45 drives the input power shaft 37 to rotate, and then the intermediate synchronous transmission mechanism drives all the output rotating shafts 40 to rotate synchronously, which is then converted into the synchronous axial sliding of the telescopic sleeve 1 42 and the telescopic sleeve 2 45. A telescopic needle 27 is provided at the end of the telescopic sleeve 1 42 away from the sliding sleeve 2 36. Thus, the telescopic needles 27 can slide laterally along the axial direction of the outer roller cover 25 through the transverse extension and retraction of the inner telescopic fork rod group 28 , thereby adjusting the distance between the telescopic needles 27 .

[0066] The sliding sleeve 2 36 includes a sliding body 1 66, and a plurality of gear mounting grooves 68 are provided on the outer edge of the sliding body 1 66. The intermediate synchronous transmission mechanism includes an intermediate transmission bevel gear 39 rotatably provided in the plurality of gear mounting grooves 68, an input bevel gear 38 provided on an end of the input power shaft 37 close to the sliding body 1 66, and an output bevel gear 41 provided on an end of the output rotating shaft 40 close to the sliding body 1 66.

[0067] Spiral grooves or thread grooves or screw threads are provided on the outer sides of the input power shaft 37 and the output rotating shaft 40 , and corresponding spiral grooves or thread grooves or screw nuts are provided on the inner sides of the telescopic sleeve 2 45 and the telescopic sleeve 1 42 .

[0068] The gear mounting grooves 68 are a plurality of conical grooves evenly distributed along the outer periphery of the sliding body 66, such as Figure 20 As shown in (a), a through groove is provided between adjacent conical grooves, such as Figure 21 As shown in (a), the angle between the axis of the conical groove corresponding to the input bevel gear 38 and the axis of the conical groove corresponding to the adjacent intermediate transmission bevel gear 39 is γ2, the angle between the axis of the conical groove corresponding to the output bevel gear 41 adjacent to the intermediate transmission bevel gear 39 and the axis of the conical groove corresponding to the intermediate transmission bevel gear 39 is γ1, and the angle between the axis of the conical groove corresponding to the input bevel gear 38 and the axis of the conical groove corresponding to the intermediate transmission bevel gear 39 is γ3, then γ3=γ1+γ2, γ1=γ2, as shown in Figure 20 (a) and Figure 21As shown in (b), the angles between the edge of the conical groove without the through-groove and the axis are δ3 and δ4, while the angles between the edge of the conical groove with the through-groove and the axis are δ1 and δ2, thus δ1 = δ2 = δ3 = δ4. A needle mount 1 (43) is provided on the end of telescopic sleeve 1 (42) away from sliding body 1 (66), with telescopic needle 27 mounted on it. A needle mount 2 (44) is provided on the side of transverse link 35 away from telescopic sleeve 2 (45), with telescopic needle 27 mounted on it.

[0069] The telescopic sleeve 42 cannot rotate along its own axis. For example, a telescopic arc segment capable of telescoping between adjacent telescopic sleeves 42 can be provided. This can prevent the telescopic sleeves 42 from rotating and adapt to the axial sliding of the telescopic sleeve 42 towards or away from the sliding body 66. Alternatively, a segment such as the following can be provided at the edge of the needle mounting seat 43 along the axis of the sliding body 66: Figure 23 As shown in the notch, a slide groove accommodating structure is provided in the outer roller cover 25 for the notch to slide, thereby preventing the telescopic sleeve 42 from rotating around its own axis.

[0070] like Figure 11-12 As shown, the extended slots 65 opened on the outer roller cover 25 diverge from the center to the two ends, and the distance between adjacent extended slots gradually becomes smaller, and the length of the extended slots 65 gradually becomes longer. This can adapt to the lateral expansion and contraction of the inner telescopic fork rod group 28, and also make the moving distance of the telescopic needle 27 from a small amount to a large amount when extending from the center of the outer roller cover 25 to the two ends. It can adapt to the situation that when the surface of the multi-layer base fabric 1 is stretched, the stretching force on the outer side of the multi-layer base fabric 1 is greater than the stretching force on the inner side, which can better stretch the multi-layer base fabric 1. The outer roller cover 25 is fixedly set on the inner rod 30, and a receiving hole 84 is opened at both ends of the outer roller cover 25. Figure 12 As shown, the included angle between adjacent protruding slots 65 is β, then β=γ3.

[0071] like Figure 20-26As shown, a second through hole 67 for the inner rod 30 to pass through is provided on the inner side of the sliding body 1 66, a third through hole 70 for the inner rod 30 to pass through is provided on the inner side of the sliding body 2 69, notches are provided on both sides of the sliding body 2 69, and a hinge shaft 1 71 is provided at the notch. The scissor rod 1 33 includes a middle straight section 73, a first arc section 74, a second arc section 75, a first hinge end 76 and a second hinge end 77. The first arc section 74 and the second arc section 75 are respectively provided at the two ends of the middle straight section 73, and the first hinge end 76 is provided at one end of the first arc section 74. The second hinged end is arranged at one end of the second arc segment 75, the first hinged end 76 and the second hinged end are flush, and the distance between the plane where the first hinged end 76 and the second hinged end are located and the axis of the inner rod 30 is smaller than the distance between the plane where the middle straight section 73 is located and the axis of the inner rod 30; the scissor rod 34 includes a lower straight section 78, a third arc segment 79 and a third hinged end 80, and the lower straight section 78 and the third hinged end 80 are respectively arranged at both ends of the third arc segment 79, and the distance between the plane where the third hinged end 80 and the inner rod 30 is smaller than the distance between the plane where the lower straight section is located and the inner rod 30.

[0072] like Figure 4-8 As shown, the first heat-insulating pressure roller group 10 and the second heat-insulating pressure roller group 11 both include a roller inner core 15 and a plurality of belt clutch outer guide sleeves 16 movably arranged on the outside of the roller inner core 15, the belt clutch outer guide sleeve 16 is connected to the roller inner core 15 through a one-way locking assembly 46, a plurality of intermediate convex rings 61 are arranged on the outer periphery of the roller inner core 15, a through hole 1 62 is arranged on the inner side of the belt clutch outer guide sleeve 16, a belt receiving groove 63 is opened on the outer side, and a receiving groove matching the intermediate convex ring 61 is opened at both ends of the through hole 1 62, the one-way locking assembly 46 includes a pendulum block 82 rotatably arranged in the belt clutch outer guide sleeve 16, a triangular receiving slot 81 is opened in the roller inner core 15, when the belt clutch outer guide sleeve 16 is engaged with the roller inner core 15, the pendulum block 82 is driven by the bias spring 83 to be clamped in the triangular receiving slot 81, and as shown Figure 8 As shown in (b), when the roller core 15 rotates clockwise, it can drive the belt clutch outer guide sleeve 16 to rotate clockwise. When the clockwise rotation speed of the belt clutch outer guide sleeve 16 is greater than that of the roller core 15, the pendulum block 82 can overcome the elastic force of the bias spring 83 so that the pendulum block 82 can slide out along one side of the triangular receiving slot 81, thereby realizing the rotation of the belt clutch outer guide sleeve 16 relative to the roller core 15.

[0073] like Figure 5As shown, the radius of the annular belt 17 surrounding the first heat-insulating pressure roller group 10 is R1, and the radius surrounding the second heat-insulating pressure roller group 11 is R2. An intermediate slot 64 is also provided on the inner side of the annular belt 17. The telescopic needle 27 can be inserted into the intermediate slot 64. When the telescopic needle 27 slides laterally along the axial direction of the base fabric processing roller group 24, it can drive the adjacent annular belts 17 to open each other. The telescopic needle 27 includes a fixed needle body and a telescopic needle head. The telescopic needle head is slidably arranged on the inner side of the fixed needle body through a telescopic drive source (such as a telescopic cylinder or a telescopic motor), so that the length can be adjusted as needed. The specific telescopic structure is common knowledge in the field and will not be described here.

[0074] like Figures 27-29 As shown, the first support plate 5 and the second support plate 6 have the same structure and both include a plate body 85. A vertical slide groove 48, a rotation hole 49, a rotation hole 50, a left semicircular arc 1 51, a right semicircular arc 1 52, a left semicircular arc 2 53 and a right semicircular arc 2 54 are provided on the plate body 85. The vertical slide groove 48 is provided at one end of the plate body 85. The vertical slider 57 is slidably provided in the vertical slide groove 48. The rotation hole 49 is provided on the upper side of the other end of the plate body 85. The left semicircular arc 1 51 and the right semicircular arc 1 52 are respectively provided on the left and right sides of the rotation hole 1 49 for the rotation of the rotation drive source 1 19 and the rotation drive source 2 20, respectively. The rotating hole 2 50 is opened on the lower side of the other end of the plate body 85, and the left semicircular arc 2 53 and the right semicircular arc 2 54 are respectively arranged on the left and right sides of the rotating hole 2 50, for the sliding of the rotating drive source 3 22 and the rotating drive source 4 23 respectively. A rotating shaft 1 55 is provided in the middle of the rocker arm 18, and a rotating shaft 2 56 is provided in the middle of the rocker arm 2 21. The rotating shaft 1 55 is inserted into the rotating hole 1 49, and the rotating shaft 2 56 is inserted into the rotating hole 2 50. The rotating shaft 1 55 and the rotating shaft 2 56 can rotate relative to the plate body 85. For example, a rotating drive source (such as a rotating motor or a rotating telescopic cylinder, not shown in the figure) can be provided to perform rotational drive.

[0075] A plurality of transverse drive sources 58 are arranged on the vertical slider 57, and the other end of the transverse drive source 58 is connected to the rotation drive source five 59. Through the telescopic action of the transverse drive source 58, the transverse position adjustment of the rotation drive source five 59 can be realized. The ends of the rotation drive source one 19, the rotation drive source two 20, the rotation drive source three 22 and the rotation drive source four 23 are provided with a receiving hole two 12 for engaging with the inner rod 30, and the end of the rotation drive source five 59 is provided with a receiving hole three 13 for engaging with the inner rod 30.

[0076] like Figure 27As shown, the rotating hole 49, the rotating hole 2 50, the left semicircular arc 1 51, the right semicircular arc 1 52, the left semicircular arc 2 53 and the right semicircular arc 2 54 have the same structure, the radius of the inner arc of the left semicircular arc 1 51 and the right semicircular arc 1 52 is r1, the radius of the outer arc is r2, the angle between the upper end of the inner arc of the left semicircular arc 1 51 and the horizontal axis is α1, the angle between the lower end of the inner arc of the left semicircular arc 1 51 and the horizontal axis is α2, the angle between the upper end of the inner arc of the right semicircular arc 1 52 and the horizontal axis is α3, and the angle between the lower end of the inner arc of the right semicircular arc 1 52 and the horizontal axis is α4, then r2>r1, α1=α4, α2=α3, preferably, α1=α2.

[0077] Preferably, the end of the telescopic needle 27 of the base fabric processing roller group 24 of the swinging base fabric stretching component 7 is a right-angle end that cooperates with the middle slot 64; the end of the telescopic needle 27 of the dynamic needling component 8 for adjusting the expansion gap between the annular belts 17 is a right-angle end that cooperates with the middle slot 64, the end of the telescopic needle 27 for inserting into the multi-layer base fabric 1 is a pointed end, and the end of the telescopic needle 27 of the base fabric processing roller group 24 of the base fabric correction component 9 is a right-angle end that cooperates with the middle slot 64.

[0078] Furthermore, a plurality of locking slots are provided in the middle slot 64 of the endless belt 17. In this way, when the base fabric correction component 9 needs to transfer the multi-layer base fabric 1 at different cross-sections at different speeds, the telescopic needle 27 can be inserted into the locking slot. By adjusting the rotational speed of the base fabric processing roller group 24, the endless belt 17 engaged with the telescopic needle 27 can generate a movement at a different speed from the first heat-insulating pressing roller group 10 and the second heat-insulating pressing roller group 11, thereby realizing the transmission adjustment of the multi-layer base fabric 1.

[0079] Furthermore, if Figure 3 As shown, only one base fabric correction component 9 is illustrated in the belt pressure wheel group 4. In order to further increase the flexibility of the equipment, there can be two base fabric correction components 9, which are respectively arranged at the upper and lower ends of the vertical slide 48, and also include a lifting drive source that can drive the vertical slider 57 to slide up and down, such as a driving motor or a lifting drive cylinder.

[0080] Furthermore, the telescopic needle 27 is detachably connected to the first and second needle mounting bases 43 and 44. Specifically, the detachable connection method may be a snap-on connection, a threaded connection, or the like. This detachable connection allows for flexible installation and configuration of the telescopic needle 27 based on actual processing requirements. Furthermore, the first and second heat-insulating roller assemblies 10 and 11 are equipped with heating devices to ensure that the glue remains in a non-solidified state, effectively stretching the upper and lower surface layers of the microfiber non-woven fabric, thereby achieving a better processing effect on the multi-layer base fabric. Preferably, the belt pressure roller assemblies 4 are detachably connected to each other.

[0081] In order to facilitate those skilled in the art to clearly understand the working principle of the production equipment of the water-based polyurethane sports shoe leather base of Example 2, the base cloth pressing device 2 is now described as follows: according to the process requirements of the multi-layer base cloth 1 to be pressed and formed, the number of belt pressure wheel groups 4 is selected, and the multi-layer base cloth 1 is wound on the belt pressure wheel group 4 in an S shape. The heating devices provided on the first heat-insulating pressure roller group 10 and the second heat-insulating pressure roller group 11 are heated. When the multi-layer base cloth 1 passes through the swinging base cloth stretching component 7, the second rocker arm 21 is driven by the rotating drive source to rotate back and forth around the rotating shaft 2 56. When the second rocker arm 21 is in a horizontal state, the two swinging base cloth stretching components 7 are both in a retracted state, such as Figure 9 As shown, at this time, the lower surface of the telescopic needle 27 is flush with the upper surface of the inner side of the endless belt 17, and the telescopic needle 27 is aligned with the middle slot 64. When the swing rod 21 continues to swing in an inclined state, the telescopic needle 27 of the swing base fabric stretching assembly 7 below the horizontal line is aligned with the middle slot 64 of the endless belt 17, and then the driving source of the swing base fabric stretching assembly 7 below the horizontal line that drives the middle rear scissor rod 1 and / or the middle front scissor rod 1 to rotate is actuated, so that the inner telescopic fork rod group 28 is in an expanded state, as shown in FIG. Figure 13 、 14As shown, at the same time, the telescopic needle 27 is in an extended state to ensure that the telescopic needle 27 can still be located in the middle slot 64. At this time, the endless belt 17 changes from a close fit to an open state, thereby driving the surface of the multi-layer base fabric 1 to stretch outward. Before the rocker arm 21 changes from horizontal to inclined and then to horizontal again, the telescopic needle 27 of the swing base fabric stretching assembly 7 below the horizontal line can all press against the endless belt 17. At the same time, the inner telescopic fork rod group 28 changes from being fully retracted to being fully extended. When the rocker arm 21 is in a horizontal state, the telescopic needle 27 retracts, and the endless belt 17 is reset without support. Since the endless belt 17 has no support in the middle, it has almost no pressure on the multi-layer base fabric 1, so that the endless belt 17 will not affect the surface of the multi-layer base fabric 1 when it is retracted and reset. , the other swinging base fabric stretching component 7 has the same action as the previous swinging base fabric stretching component 7 when it tilts downward, and it will not be repeated here. By swinging the base fabric stretching component 7, it forms a continuous stretching of the multi-layer base fabric 1, ensuring the molding quality of the multi-layer base fabric 1; in addition, when the multi-layer base fabric 1 reaches the dynamic needling component 8, the telescopic needle 27 of a swinging base fabric stretching component 7 in the dynamic needling component 8 is inserted into the middle slot 64 of the endless belt 17, and the telescopic degree of the inner telescopic fork rod group 28 is adjusted as needed, so that the opening degree of the endless belt 17 can be selected, and the telescopic needle 27 of the other swinging base fabric stretching component 7 can enter the multi-layer base fabric 1 from the gap between the adjacent endless belts 17, and by continuously rotating the base The cloth processing roller group 24 enables the telescopic needle 27 to continuously perform acupuncture operations. Compared with the existing fixed acupuncture gap, it can select the acupuncture spacing and acupuncture frequency according to needs; when the transmitted multi-layer base cloth 1 is deflected to the left or right as a whole, the base cloth correction component 9 is driven to slide along the vertical slide 48 and contact the endless belt 17, and the telescopic needle 27 is inserted into the middle slot 64, and then the transverse driving source 58 is driven to slide to the left or right according to the direction of the deflection, so that the multi-layer base cloth 1 that is deflected to the left or right can be corrected; in addition, if the multi-layer base cloth 1 is conveyed, the middle conveying is fast and the two sides conveying are slow, or the middle conveying is slow and the two sides conveying are slow, the corresponding telescopic needle 27 of the slow conveying is inserted into The locking slots in the middle slot 64 of the corresponding annular belt 17 and the other telescopic needles 27 are retracted, and then the base fabric processing roller group 24 of the base fabric correction component 9 is driven to rotate in the same direction as the first heat-insulating pressure roller group 10 and the second heat-insulating pressure roller group 11, and at the same time, the rotation speed of the base fabric processing roller group 24 is greater than the first heat-insulating pressure roller group 10 and / or the second heat-insulating pressure roller group 11, so that the belt clutch outer guide sleeve 16 rotates relative to the roller inner core 15, and the one-way locking component 46 at the corresponding annular belt 17 is disengaged, so that the annular belt 17 can be transmitted at a faster speed than other annular belts 17, thereby compensating for the defect of slow transmission, and finally making the entire multi-layer base fabric 1 evenly transmitted over the entire cross section.
